 wherein the clamp assembly comprises a first clamp and a second clamp, the first clamp clamps a first side of the flexible display panel, the second clamp clamps a second side of the flexible display panel, and the first side is opposite to the second side, wherein the rotary drive device is connected to the first clamp and the second clamp, and the rotary drive device drives simultaneous movement and synchronous rotation of the first clamp and the second clamp; 
 wherein the pressing block assembly comprises a pressing block, and a surface of the pressing block is provided with a curved protrusion adapted to an inner contour of the curved cover plate. 
 
     
     
       2. The adhering device of  claim 1 , wherein a clamping surface of the first clamp and a clamping surface of the second clamp are provided with an anti-adhesive layer. 
     
     
       3. The adhering device of  claim 1 , wherein the pressing block assembly further comprises a rising drive device, the rising drive device is connected to the pressing block, and the rising drive device drives the pressing block. 
     
     
       4. The adhering device of  claim 1 , wherein the chamber is provided with an air pumping hole; the adhering device further comprises a vacuuming device, and the vacuuming device is connected to the air pumping hole for vacuuming the chamber. 
     
     
       5. An adhering device for adhering a curved cover plate to a flexible display panel, the adhering device comprising:
 a chamber, wherein the chamber comprises a first portion and a second portion, and the first portion is detachably connected to the second portion; 
 a carrying platform, the carrying platform disposed in the chamber, wherein the carrying platform is provided with a groove for mounting the curved cover plate therein; 
 a pressing block assembly disposed in the chamber, wherein the pressing block assembly supports the flexible display panel and moves the flexible display panel at a preset speed toward the curved cover plate to adhere to the curved cover plate; and 
 a clamp assembly, disposed in the chamber, wherein the clamp assembly clamps the flexible display panel, the clamp assembly comprises a rotary drive device, and when the flexible display panel is moved toward the curved cover plate at the preset speed, the rotary drive device controls the clamp assembly to rotate until the flexible display panel and the curved cover plate are completely adhered to each other; 
 wherein the clamp assembly comprises a first clamp and a second clamp, the first clamp clamps a first side of the flexible display panel, the second clamp clamps a second side of the flexible display panel, the first side is opposite to the second side, wherein the rotary drive device is connected to the first clamp and the second clamp, and the rotary drive device drives simultaneous movement and synchronous rotation of the first clamp and the second clamp. 
 
     
     
       6. The adhering device of  claim 5 , wherein a clamping surface of the first clamp and a clamping surface of the second clamp are provided with an anti-adhesive layer. 
     
     
       7. The adhering device of  claim 5 , wherein the chamber is provided with an air pumping hole, the adhering device further comprises a vacuuming device, and the vacuuming device is connected to the air pumping hole for vacuuming the chamber. 
     
     
       8. The adhering device of  claim 5 , wherein the pressing block assembly further comprises a rising drive device, the rising drive device is connected to a pressing block, and the rising drive device drives the pressing block. 
     
     
       9. An adhering method for adhering a curved cover plate to a flexible display panel comprising the adhering device as claimed in  claim 5 , the adhering method comprising the steps of:
 flexing the flexible display panel to a predetermined arc and clamping the flexible display panel by the clamp assembly; 
 vacuuming the chamber and raising the flexible display panel to a preset adhering position; 
 controlling the pressing block assembly to move the flexible display panel at the preset speed to adhere to the curved cover plate, and controlling the clamp assembly to rotate at a preset rotational speed until the flexible display panel and the curved cover plate are completely adhered to each other, and then the clamp assembly is separated from the display panel. 
 
     
     
       10. The adhering method of  claim 9 , wherein the preset speed coordinates with the preset rotating speed through a simulation calculation.
